I compiled each of these tests using an LLVM-based compiler, since LDC seems to be the best option for D compilation in terms of performance. On my x86_64 Arch Linux installation I used the following packages:
clang 3.6.0-3

How do I safely pass objects, especially STL objects, to and from a DLL?

In a dynamic language, if the delegatee is i...
Javascript when to use prototypes
...So in those situations where (in C# or Java) you would have derived from a base class to gain default behaviour, which you then make small modifications to via overrides, then in JavaScript, prototypical inheritance makes sense.
However, if you're in a situation where you would have used interfaces...

C++ new int[0] — will it allocate memory?
...C++ isn't so strong with forbidding zero sized objects. Think of the empty base class optimization: Here too, an empty base class sub-object may have size zero.
